Grande non-fat latte for Princess Leia!
I have actually talked about this here before.
I used to do that - give a fake name at Starbucks. You know, it's just easier than trying to spell my name for them & then have them fuck it all up anyway. Sometimes when they ask me my name, if I'm feeling especially ornery, I just say, "Kalisah, with a 'K'." and I leave them at that. They still don't get it right, but it's sometimes fun to see how they try.
I actually still do give a fake name if I'm not in my regular Starbucks. They know me there so it's rather pointless. Some of the names I've given include: Kate, Katie, Drew, Emmy, Emma, Rachel, Carrie, Evan and Evie. My best Starbucks name though, was "Brando."
The article mentions that some people like to use Star Wars names, which seems a little over the top for me.
Do you give fake names? What do you use?
